I had a similar brain cramp in February of 2011; I accidentally no-indexed my home page for about a whole month. Doh!

It took about a week for things to sort themselves out. However, it seems that LATELY there are many reports of google taking a longer time to respond to changes / index new content, so it might be a bit for things to work themselves out.

If no, then what steps should I take to resolve / fix this issue?

Warning: Marginal advice with no scientific basis behind it to follow:

Go in to webmaster tools and do a fetch as googlebot on some of your key pages, and then go ahead and "submit" the URL to google. I think you can only do that with a total of 20 pages per month, so maybe just pick out some key ones?

Then, and this is the most important part; find a nice quiet place, sit down with a nice glass of Irish whiskey, and crank up some of your favorite music.

Probably these two steps are about as equally effective in getting thins resolved with google :)

thanks guys, i have fetched and submitted few of the pages to the google index in wmt, like u guys adviced... The submissions available to me have been reduced to zero now! is there a daily limit to it?
